United States Patent C) U.S. Cl. 202-241 4 Claims ABSTRACT OF THEDISCLOSURE A coke oven pusher machine has a supporting arm eX- tendingtherefrom and movable longitudinally toward and away from the coke ovenchamber. A connecting member is pivotally secured to the end of thesupporting arm and has door jamb cleaning apparatus and door handlingapparatus secured thereto in angular spaced relation to each other. Asuitable drive means `is provided to pivot the connecting memberrelative to the end of the supporting arm to position either the doorjamb cleaning apparatus or the door handling apparatus in operativeposition with the coke oven door jamb. With this arrangement, the cokeoven door jamb can be cleaned and the coke oven door rcplaced withoutmoving the pusher machine.

BACKGROUND OF THE INVENTION (1) Field of the invention This inventionrelates to a combined coke oven door jamb cleaning apparatus and doorhandling apparatus and more particularly to a support member thatpivotally supports both the door jamb cleaning apparatus and the doorhandling apparatus from a common supporting arm.

(2) Description of the prior art In horizontal by-product coke ovens,the coke oven chambers are sealed at their opposite ends by coke ovendoors. On the machine side of the coke oven battery, a pusher machineincludes separate apparatus to remove and support the coke oven door,push the charge of coke and level a new charge of coal to be coked.Separate apparatus is provided to clean the door jamb before the door isreplaced. When space conditions between the coke oven battery and thefront portion of the retracted pushing ram permit, the door jambcleaning apparatus is moved into position between the coke oven batteryand the coke pusher machine without moving the pusher machine. Where,however, the space conditions on the machine side of the coke oven arelimited, the pusher machine must be moved away from the coke ovenchamber after the pushing operation to provide room for positioning thedoor jamb cleaning lapparatus in operative position. This increases .thetotal operating time required to push the charge of coke, clean the doorjamb and recharge the oven with coal to be coked.

There have been proposals in the past to combine the coke oven door jambcleaning apparatus with the pusher ram. With this arrangement, the cokeis first pushed from 3,577,321 Patented May 4, 1971 the coke oven by thepusher ram and then the coke oven door jamb cleaning device removes thecarbonaceous material from the door jamb so that the door may bereplaced to effectively seal the coke oven chamber. The door that isremoved from the coke oven is separately supported on a door liftinghead of the door handling apparatus and the pusher machine is then movedlaterally to move the door handling apparatus into position toreposition the coke oven door. There is a need for apparatus thateliminates the movement of the pusher machine during the door jambcleaning operation and the reposi-tioning of the coke oven door insealing relation with the coke oven chamber.

The hereinafter described invention relates to a combined door jambcleaning apparatus and door handling apparatus that are angularlysecured to a common connecting member. The connecting member ispivotally secured to a support arm that is movable longitudinallyrelative to the coke oven chamber. The door jamb cleaning apparatus ispositioned at an angle of about to the door handling apparatus and theconnecting member is pivotally secured to the support arm. After thecoke has been pushed from the coke oven chamber by the pusher ram, thepusher machine is moved laterally to the coke oven chamber until thedoor jamb cleaning apparatus is aligned with the empty coke ovenchamber. The supporting arm moves longitudinally toward the coke ovenchamber and position the door jamb cleaning apparatus in operativeposition to remove the carbonaceous material from the door jamb. Afterthe cleaning operation is completed, the support arm is retracted awayfrom the coke oven chamber and the connecting member is pivoted about avertical pivot axis to move the door handling apparatus into alignedrelation with the coke oven chamber. The support arm is then advancedtoward the coke oven chamber and the door is positioned in the door jamband secured therein. With this arrangement, the door jamb cleaningapparatus cleans the door jamb and the door is repositioned in the doorjamb without moving the coke pusher machine. It is, therefore, no longernecessary to move the coke pusher machine during the cleaning of thedoor jamb and the replacing of the coke oven door.

Accordingly, 4the principal object of this invention is to provideapparatus for cleaning the coke oven door jamb and replacing the cokeoven door without moving the pusher machine.

Another object of this invention is to provide a coke pusher machinewith apparatus for angularly connecting the door jamb cleaning apparatusand the door handling apparatus and pivotally securing the connectedapparatus to a longitudinally movable supporting arm tha-t forms a partof the pushing machine.

These and other objects and advantages of this invention will be morecompletely disclosed and described in the following specification, theaccompanying drawings and the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. l is a fragmentary schema-ticplan view of the machine side of a horizontal coke oven battery,partially in section, with the pusher machine positioned adjacentthereto and illustrating the door jamb cleaning apparatus in operativeposition to clean the door jamb.

FIG. 2 is a view similar to FIG. l illustrating the door handlingapparatus in position to replace the coke oven door.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, afragmentary portion of the pusher side of a coke oven is generallydesignated by the numeral and includes a plurality of horizontal cokingchambers 12 with heating walls 14 therebetween. Buckstays 16 extendvertically on opposite sides of the coke oven chambers 12 along thepusher side wall. Coke oven doors designated by the numeral 18 arepositioned in abutting relation with rectangular door jambs 20 to sealthe coke oven chambers 12 during the coking operation.

A pusher machine generally designated by the numeral 22 is mounted onrails 24 and is operable to move along the machine side of the coke oven10. The pusher machine 22 includes a leveling bar 26, a pusher ram 28and a support member 30 .to -which a connecting member 32 is pivotallysecured. The connecting member 32 has a door jamb cleaning device 34 anda door handling device 36 secured thereto. The door jamb cleaning devicemay be of conventional construction similar to that illus- -trated inU.S. Pat. 2,391,214 or U.S. Pat. 3,119,135.

The door handling apparatus 36 includes a door lifting head 38 which isoperable to be connected to the coke oven door 18 and unlatch and removethe door from the door jamb 20. The door handling apparatus 36 securedto the connecting member 32 may also be of conventional construction, asfor example, the door handling devicex illustrated in US. Pat.2,391,214.

The connecting member 32 is pivotally secured to the support member 30-about a vertical pivot pin 40. Suitable drive means, not illustrated, isprovided to pivot the connecting member 32 about the axis of pivot pin40 to thereby position either the door jamb cleaning device 34 or thedoor handling device 36 in operative aligned relation with the coke ovenchamber 12. The support member 30 has a trolley 42 with trolley wheels44 suitabily supported on rails 46 on the pusher machine 22. Othersuitable drive means are provided to reciprocate and move the supportmember 30 toward and away from the coke oven chambers 12 by means of thetrolley 42.

With the above door jamb cleaning device 34 and door handling device 36secured to the connecting member 32 and extending therefrom at an angleof about 90 to each other, it is now possible to clean the coke ovendoor jamb 20 and replace the coke oven door 18 without moving the pushermachine 22 on the rails 24.

After pushing the coke from the coke oven chamber 12 by the pusher ram28, the pusher machine 22 is moved to the position illustrated in FIG.1, opposite the empty coking chamber 12. The pusher machine 22 is movedalong the rails 24 until the axis of the support member 30 is alignedwith the axis of the empty coking chamber 12. The supporting member 30is in a retracted position where both the door'jamb cleaning device 34and the door handling device 36` are spaced rearwardly from thebuckstays 16. When the support member 30 is aligned with the coke ovenchamber 12, a drive means is actuated to rotate the connecting member 32about the axis of pivot pin 40 to align the door jamb cleaning device 34with the coke oven chamber 12 as is illustrated in FIG. 1. The supportmember 30 is then moved toward the coke oven chamber 12 until the doorjamb cleaning device is in operative position as illustrated in FIG. 1to remove the carbonaceous residue from the door jamb 20. After the doorjamb 20` has been cleaned by the door jamb cleaning device 34, thesupport member 30 is retracted as is illustrated in FIG. 2 and theconnecting member 32 rotated about the pivot pin 40 to align the doorhandling device 36 with the coke oven chamber 12. The support member 30is then advanced along the rails 46 to bring the door 18 into abuttingrelation with the door jamb 20 and the door is then locked in position.With the above described apparatus the time consuming operation ofmoving the coke pusher machine 22 along the rails 24 during the doorjamb cleaning operation and thereafter repositioning the pusher machine22 to replace the door 18 has been eliminated.
